TS-Optics CCD Reducer 2\u2033 0,67\u00d7 - For RC, refractors and Maksutov-Cassegrain<\/h3>\n

Visit TS-Optics CCD Reducer 0,67\u00d7<\/strong> is a versatile focal reducer originally designed for telescopes. Ritchey-Chr\u00e9tien<\/strong>but also perfectly suited to Celestron EHD, Meade ACF, Maksutov-Cassegrain<\/strong> and f\/8 or slower refractors<\/strong> with sufficient backfocus. It allows the focal length to be reduced and the f\/ ratio to be accelerated, halving exposure times while enlarging the field of view.<\/p>\n

Highlights<\/h3>\n
    \n
  • Reduction 0.67\u00d7<\/strong> : an RC f\/8 becomes f\/5.3, an f\/10 becomes f\/6.7 \u2192 exposure times reduced by more than 50 %.<\/li>\n
  • Simple connection<\/strong> 2\u2033 standard barrel compatible with all 2\u2033 eyepiece holders.<\/li>\n
  • M48 thread on camera side<\/strong> 85 mm optimum backfocus (70-90 mm usable).<\/li>\n
  • 2\u2033 filter thread<\/strong> integrated on the telescope side \u2192 direct compatibility with your filters.<\/li>\n
  • Illuminated field<\/strong> up to 29 mm, perfect for sensors APS-C<\/strong> (DSLR and astro cameras).<\/li>\n
  • Versatile<\/strong> photo as a priority, but can be used as a visual with 1.25\u2033 angled return.<\/li>\n<\/ul>\n

    Why use a 0.67\u00d7 CCD reducer?<\/h3>\n

    In astrophotography, optical speed is crucial: reducing the focal length means widening the field while capturing more signal per unit of time. With this reducer, your telescopes become brighter, your shorter exposures<\/strong> and your images richer in detail. It's the ideal accessory for photographing diffuse nebulae and wide-field galaxies.<\/p>\n

    Compatibility<\/h3>\n

    The CCD47 is optimized for RC GSO\/TS\/AstroTech<\/strong>but works equally well with other instruments featuring a 2\u2033 eyepiece holder. It is particularly recommended for :<\/p>\n

      \n
    • RC<\/strong> excellent illumination and correction up to APS-C.<\/strong><\/li>\n
    • f\/8+ refractors<\/strong> good correction with sufficient backfocus.<\/li>\n
    • Maksutov-Cassegrain<\/strong> improves imaging speed.<\/li>\n
    • Celestron EHD \/ Meade ACF<\/strong> wider field and shorter exposure times.<\/li>\n<\/ul>\n

      Possible adaptations<\/h3>\n
        \n
      • DSLR<\/strong> via M48 thread \u2192 e.g. SKM48-EOS adapter for Canon.<\/li>\n
      • CCD via T2<\/strong> : TSFA2<\/em> (38.2 mm, extension) or TSM48-T2<\/em> (3.5 mm, compact for OAG\/filter wheels).<\/li>\n<\/ul>\n
